=> You currently have modules installed globally with `npm`. These will no
=> longer be linked to the active version of Node when you install a new node
=> with `nvm`; and they may (depending on how you construct your `$PATH`)
=> override the binaries of modules installed with `nvm`:

=> If you wish to uninstall them at a later point (or re-install them under your
=> `nvm` Nodes), you can remove them from the system Node as follows:

     $ nvm use system
     $ npm uninstall -g a_module

=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Installing RVM to /Users/panda8z/.rvm/
    Adding rvm PATH line to /Users/panda8z/.profile /Users/panda8z/.mkshrc /Users/panda8z/.bashrc /Users/panda8z/.zshrc.
    Adding rvm loading line to /Users/panda8z/.profile /Users/panda8z/.bash_profile /Users/panda8z/.zlogin.
Installation of RVM in /Users/panda8z/.rvm/ is almost complete:

  * To start using RVM you need to run `source /Users/panda8z/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.
